Contamination Risk Assessment & Remediation Strategy Generator
Evaluate contaminated sites and develop EPA-compliant cleanup strategies with risk quantification
What You Can Do
You can conduct comprehensive site contamination assessments by inputting field investigation data, soil/groundwater analytical results, and site-specific exposure pathways. Claude analyzes the contamination against regulatory standards, quantifies human health and ecological risks, and generates multiple remediation alternatives (excavation, soil vapor extraction, pump-and-treat, in-situ oxidation, capping) with cost-benefit analysis and regulatory justification. The output produces documentation-ready risk assessments and remedial action objectives suitable for RI/FS reports and Records of Decision.
Features
Input soil, groundwater, and vapor intrusion sampling results to establish baseline contamination profiles and identify hotspots
Systematically evaluate residential, commercial, and industrial exposure scenarios including ingestion, inhalation, and dermal contact routes
Calculate hazard quotients and carcinogenic risk estimates aligned with EPA RAGS guidance and state-specific risk thresholds
Generate defensible RAOs tied to site-specific target levels (SSTLs) and regulatory endpoints
Evaluate multiple cleanup technologies with cost estimates, timeline projections, and regulatory compliance documentation
Cross-reference RCRA, CERCLA, state corrective action rules, and RBCA protocols to justify selected remedies
Structure financial comparisons between technologies accounting for capital, O&M, and risk reduction benefits
Produce RI/FS-ready summaries, ROD supporting materials, and regulatory agency correspondence templates
Example Output
Site Risk Assessment Summary:
- Contamination Profile: TCE in groundwater (850 μg/L vs. 5 μg/L MCL); naphthalene in soil (2.8 mg/kg vs. 0.56 mg/kg RSL)
- Exposure Pathways: Groundwater ingestion (residential well scenario); soil direct contact (child play area); vapor intrusion (commercial building)
- Risk Calculation: HQ = 3.2 (groundwater ingestion); Cancer risk = 8.2E-05 (exceeds 1E-06 threshold)
Recommended Remedial Strategy:
- Pump-and-treat groundwater extraction (5-year operation, $450K capital + $85K/year O&M)
- In-situ chemical oxidation for vadose zone (30-day mobilization, $180K)
- Institutional controls/deed notice for long-term monitoring
Regulatory Justification: Strategy complies with EPA RAGS risk-based corrective action and achieves 90-day site stabilization target per State Corrective Action Rule Section 3745-27-02(D).
